Yes i did. There a great cheap alternative for stock shocks and if u want a lift especially with stock A arms. But ultimately not your end all best way to go about it. With the spacers, u get a stiffer ride out of compressing the springs and your rear pitch on the tires will change.
you can build the spacer lift yourself very cheap with steel black pipe. You can cut it to a few different lengths as well.
I added them 3 years ago because I have a lot of extra weight up front and use my snow plow. Works well for me and still sets level but that might be due to it being the deluxe with the rear leveling springs but not sure. Have had zero problems.
